Hinge, in particular for coupled window constructions

ABSTRACT

A hinge for coupled window constructions comprising hinge blades and a pivot pin connecting said blades by means of cylindrical bearing burhings formed in said blades. The pivot pin is of an oval cross-section permitting a mutual displacement of said bearing blades in the direction of the smaller axis of the ovat section but preventing a mutual displacement in the direction of the longer axis of the oval section.

UNITED STATES PATENTS 3 Cl 8 D F 969,926 9/1910 Wightman 16/168 A Q: 7A 10 7 HINGE, IN PARTICULAR FOR COUPLED WINDOW CONSTRUCTIONS The subject of the present invention is a hinge for two components mounted pivotably to each other, in particular for the sash halves of a coupled window casement, which hinge comprises at least two hinge blades and connecting pivot pin, which is rotably mounted in bearing bushings formed in the hinge blades.

In coupled window constructions it is important not only that the sash halves of the casement can be mounted to each other pivotably so that the sash halves can be opened for glass work, cleaning, etc., but also that the sash halves that have been pivoted together can be locked to each other and pressed tightly against each other so as to seal the space between them. So far, it has been usual to use separate means for the pressing together, such as tightening screws and similar things.

A purpose of the present invention is to obtain a hinge that eliminates the above drawback, and this is achieved by means of the hinge in accordance with the present invention, which is characterized in that the pivot pin is of an oval cross-section, whereby the longer axis of the oval section substantially corresponds to the inner diameter of the bearing bushings so as to prevent mutual movements of the hinge blades in the direction of this axis and the shorter axis is smaller than the inner diameter of the bearing bushings so as to allow mutual movements of the hinge blades in the direction of the latter axis.

In accordance with the invention, a hinge of a very simple construction is obtained, which does not only operate as a conventional hinge allowing pivoting movement between coupled components but which also makes it possible to tighten the components against each other. This is permitted by the oval crosssection form of the pivot pin, which allows the hinge blades to move in relation to each other off the coaxial position of the bearing bushings when the pivot pin has been rotated to a certain loosening position, but forces the hinge blades back to the coaxial position when the pivot pin is rotated 90 from said loosening position into the tightening position. The hinge in accordance with the present invention thus operates both as a hinge proper and as a tigntening means. Nevertheless, the hinge in accordance with the present invention can be installed in the same way as ordinary blade hinges. Since the pivot pin can be made as having an oval section all over its length, the manufacturing of the pivot pin causes no difficulties.

In the Swiss Pat. No. 316,107 a pivot pin for a door is described. The section of the pivot pin is circular over the entire length, but the pivot pin has peg sections which have eccentrically positioned axes and by means of which it is possible to produce a certain tightening effect by rotating the pin. The eccentric construction of the pin, however, causes movement of the door in the direction of the wall plane at the same time as the door is moved perpendicularly towards the plane of the wall. Such a tightening movement in two directions is, however, not desirable and not always even possible in window constructions. In the present invention, the tightening of the hinge can be made to take place by means of a shifting movement in one direction only, perpendicularly towards the plane of the window.

The invention will be described more closely below with reference to the attached drawings, in which FIG. 1 shows a preferable movement of the hinge in accordance with the invention as a side view partly in section,

FIG. 2 shows the same as viewed from above,

FIGS. 3 and 4 show the pivot pin as a side view in two different positions,

FIGS. 5 and 6 show diagrammatic views on a larger scale of the principle of operation of the hinge in accordance with the invention in the loosening position and in the tightening position, respectively,

FIG. 7 shows a horizontal section of a window construction in which the hinge has been used, and

FIG. 8 shows a window construction as a front view on a smaller scale.

The hinge shown in the drawings comprises three hinge blades 1, 2 and 3 and a connecting pivot pin 4.

The hinge blades 1 and 3 are intended to be fastened to one element and the hinge blade 2 to the other element. The hinge blades are conventionally provided with bearing bushings la, 2a and 3a, which constitute holes lb, 2b and 3b of circular sections. A transversal arm 5 is fastened to the end of the pivot pin.

As can be seen in particular from FIGS. 3 to 6, the pivot pin 4 has an oval cross-section. The longer axis of its cross-section substantially corresponds to the inner diameter of the bearing bushing, whereas the shorter axis is considerably shorter than the inner diameter. This is why the bearing bushings I, 2 and 2, 3, respectively, can move in the direction of the arrow A off the coaxial position when the pivot pin is turned into the position shown in FIG. 5. When the pivot pin is, by means of the arm, rotated into the position shown in FIG. 6, the bearing bushings are forced to move towards each other and to assume coaxial positions in relation to each other. It is noticed that the hinge in this way operates both as a hinge and as a tightening means, as will be described below.

The window construction shown in FIGS. 7 and 8 comprises a frame 6 and a coupled casement 7 mounted thereon pivotably, which frame comprises two sash halves 7A and 78. Two hinges have been fastened on each vertical side of the casement, whereby the hinges 8 positioned on one side operate as the pivoting hinges of the sash halves and the hinges 9 positioned on the opposite side operate as locking devices of the sash halves. Hereby the hinge blades 1 and 3 of both hinges have been fastened in the usual way to one sash half 7A and the hinge blade 2 to the other sash half.

FIG. 7 shows the pivot pin 4 in the tightening position, i.e. in the position in which the bearing bushings of the hinge blades are positioned mutually coaxially pressing the sash halves tightly against each other by means of the packing 10. When the pivot pins of both hinge pairs 8, 9 are in the position shown in FIG. 7, the sash halves can be pressed tightly into proper location and into the normal operating position by means of both vertical sides of the easement.

When the pivot pins of the hinges are turned 90 outwards, the bearing bushings of the hinges can move somewhat off each other in the direction of the arrow A, whereby the tightening is relieved and the pivot pins of the hinges 9 on one side of the casement can be removed. After this time sash halves can be pivoted open on the hinges 8. When the sash halves of the easement are coupled together, the steps are taken in the contrary order.

The drawing and the related description are only intended to illustrate the idea of the invention. in its details the hinge in accordance with the invention may show even considerable variability within the scope of the patent claims. Although the invention has been described above in connection with a window construction, it is evident that the hinge in accordance with the invention may also have several other objects of use.

1 claim:

1. An improved hinge for two components connected pivotally to each other, in particular for the sash halves of a coupled window casement which hinge comprises at least two hinge blades formed with bearing bushings, and a connecting pivot pin which is rotatably mounted in the bearing bushings, the improvement residing in that the pivot pin is of oval cross-section with the length of the longer axis of the oval section substantially corresponding to the diameter of the interior of the bearing bushings so as to prevent relative movement of the hinge blades in directions along said longer axis and the length of the shorter axis smaller than the diameter of the interior of the bearing bushings so as to permit relative movement of the hinge blades in directions along said shorter axis.

2. A hinge as claimed in claim I, wherein the pivot pin is oval over its entire length.

3. A hinge as claimed in claim 1, wherein the pivot pin is provided at one end with a transverse arm to bring about rotation of the pivot pin.
